The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the menu for Kennebunk Beach over the next couple of weeks.
Honestly, we're looking at a pretty flat spell for a while. The first twelve days or so are a write-off for any proper surfing. The swell is tiny, the energy is weak, and most of the time the conditions are just plain poor. There's a bit of a gap there with nothing to recommend.
Things finally start to show a pulse around Wednesday, the 19th of August. The morning will see a glassy 3ft swell from the southeast, but it's short period, and the energy is only moderate (142). It's surfable, but nothing to write home about. The wind is glassy though, so it'll be clean.
The real standout, the only one worth getting excited about, is Friday morning, the 21st of August. We've got a 8ft swell from the east, pushing through with strong energy (683). The period is a short 7 seconds, so it's going to be a bit fat and dumpy, best for the more experienced crew. The wind is glassy, making for clean conditions. This is big, powerful, and will be a proper session for the experts. The afternoon gets messy with a cross-onshore wind, so make the most of the morning.
The water temp is sitting at 64°, which is about average for this time of year, so no surprises there.
Keep in mind, Kennebunk Beach is a sheltered spot, and it's fairly consistent, but it can get crowded. As for the rest of the outlook, it's a long wait for that one Friday morning window.
Stay tuned.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
